F2FS Encryption: Enhancing Storage Security and Performance

F2FS (Flash-Friendly File System) is a modern file system designed specifically for flash-based storage devices. In this post, we'll explore F2FS encryption and how to set it up, along with some advanced features to optimize your storage.

To create an F2FS partition with encryption support, use the following command:
mkfs.f2fs -O extra_attr,inode_checksum,sb_checksum,compression /dev/nvme0n1p3 -f

Let's break down the options:

• extra_attr: Enables extended attributes, which are necessary for encryption.
• inode_checksum: Adds checksums to inodes for improved data integrity.
• sb_checksum: Enables superblock checksums for additional protection.
• compression: Activates built-in compression support.

To mount your F2FS partition with encryption add the following line to your /etc/fstab file:
/dev/nvme0n1p3 / f2fs defaults,compress_algorithm=lz4:5,compress_chksum,atgc,gc_merge,noatime 0 1

Explanation:

• compress_algorithm=lz4:5: Uses LZ4 compression with a compression level of 5 (range: 1-6).
• compress_chksum: Enables checksum for compressed data.
• atgc: Activates Active Garbage Collection for improved performance.
• gc_merge: Merges segments during garbage collection for better space utilization.
• noatime: Disables updating access times, reducing write operations.
